    摘要： A plasma arc torch is provided that comprises a set of torch consumable components secured to a torch head, wherein a supply of cooling fluid flows coaxially through the torch to cool torch components and a supply of plasma gas and secondary gas flows through the torch to generate and stabilize a plasma stream for operations such as cutting workpieces. The torch consumable components, in part, comprise an electrode and a tip that include a variety of configurations for improved cooling, electrical contact, and attachment to adjacent torch components. Further, a consumables cartridge is provided for ease of use and replacement of the torch consumable components. Additionally, methods of operating the plasma arc torch at relatively high current levels are also provided by the present invention.

    摘要： Plasma arc torches are provided that include a mounting for an electrode and a coolant tube telescopingly mounted on the plasma arc torch to engage and deliver coolant to electrodes of different sizes mounted in the mounting. The telescopingly mounted coolant tube may extend to a closed position in which coolant does not flow when no electrode is mounted in the mounting. The telescopingly mounted coolant tube may further be used to electrically connect a cathodic member with the electrode mounted in the mounting.

    摘要： A cooling system for a plasma arc torch is provided that comprises a coaxial fluid flow that improves cooling of components within the plasma arc torch and that provides a more compact torch design. The coaxial fluid flow, namely, the cooling fluid flow, is distributed circumferentially about the central longitudinal axis of the torch and is flowing in the same direction at any radial location from the central longitudinal axis. The cooling fluid flows distally towards the consumable components, then proximally towards the torch head, then distally again, and then proximally again for recirculation. Additionally, both the plasma gas flow and the secondary gas flow are also flowing coaxially in addition to the cooling fluid flow.
